Farsens S.L. has introduced an RFID sensor tag that can transmit a unique identifier and associated temperature measurement data to a commercial EPC C1G2 reader without the need for a battery on the sensor tag. The Pyros-TGT2-DWB features a 103GT-2 NTC thermistor (10K) from Semitec with a measurement range from -10°C to 120°C with an accuracy of ±0.5°C.

The device also offers an extended temperature range from -30°C to 300°C with an accuracy of ±3°C while the actual RFID tag operation range is -30°C to 85°C. The tag comes in a variety of antenna designs and sizes to adapt the performance to the required application in the 860-960MHz band.


The reading distance for the battery-free thermistor tag is about 1.5m and it can be embedded in a variety of materials such as plastics or concrete. It can also be encapsulated in an IP67 or IP68 casing for usage in harsh environments.
